To make the most of diagnostic equipment used in chemical processing, technicians must stretch their knowledge of control valves and related diagnostic equipment that keeps tabs on valve health and safety.
Increasing interest will translate into far more monitoring applications. The worldwide market for wireless technology will grow 26% annually over the next few years, forecasts the ARC Advisory Group. Vendors are responding and key concerns are being addressed.
Consider a variety of factors to select a unit that comes the closest. What steam traps lack in size, they make up for in numbers. In a typical steam plant, their numbers range from several hundred in a large steam plant to more than 20,000 in refinery or chemical complexes.
A profit-per minute metric can really optimize operations. The chemical industry is discovering that it needs better tools to help capitalize on the products and maximize profits to generate cash faster. It needs a new metric: profit per minute.
Production managers, quality control managers and maintenance engineers alike have encountered weigh cells that never worked properly. Why? Why have so many switched from a supposedly high accuracy load cell solution to old fashioned level probes or sight glasses? This article touches on the worst culprits for problems and how to avoid them.

Senior Editor Dirk Willard discusses Shigeo Shingo's take on mistake-proofing, or Poke Yoke, if you speak Japanese. The practice suggests the following devices: eliminate redesign, facilitate guide, mitigate lessen the damage caused by the error, or flag identify the error.
Quest for more reliable readings prompts development of tougher and more-intelligent sensors. While pH control often plays a crucial role in processing, achieving reliable readings remains challenging at many sites. After all, pH sensors frequently serve in aggressive chemical environments.
